Which command will configure one side of an EtherChannel, when the other side is configured with on mode?

A.	SwitchA(config-if)# channel-group 1 mode on
	SwitchB(config-if)# channel-group 1 mode on
B.	SwitchA(config-if)# channel-group 1 mode desirable
	SwitchB(config-if)# channel-group 1 mode desirable
C.	SwitchA(config-if)# switchport channel-group 1 mode desirable
	SwitchB(config-if)# switchport channel-group 1 mode desirable
D.	SwitchA(config-if)# switchport channel-group 1 mode on
	SwitchB(config-if)# switchport channel-group 1 mode on

A. When the on mode is used, it means that no aggregation protocol will be used. On the adjacent switch, you must use the on mode.
